TELEGRAPH-POLE.

SPECIFICATION forming part Of Letters Patent NO. 406,406, dated July 2,1889.

Application filed October 8, 1888. Serial No. 287,544. (No model.)

To aZZ whom it may concern; quirements. These standards are secured to-Be it known that 1, CHARLES M. RUSSELL, gether by a series of bracketsor spiders D, a citizen of the United States, residing at which willpreferably be made of cast-iron, Bowling Green, in the county of lVarrenand the standards being extended through vertical State of Kentucky,have invented certain new holes in the arms of said brackets, saidbrack- 5 5 and useful Improvements in Telegraph-Poles; ets being ofdifferent sizes, with the standardand I do hereby declare the followingto be a holes diiferent distances apart to correspond full, clear, andexact description of the invento the area of the tripod at the placewhere tion, such as will enable others skilled in the the brackets areto be secured. The upper IO art to which it appertains to make and usebracket will be held in place upon the rods, the same. preferably bynuts a, as shown in Fig. 1,

This invention relates to improvements in while the lower one will restupon (prefertelegraph-poles and insulators therefor, the ably) afoundation-stone b, the standards beobject of the invention being toprovide a ing extended entirely through said stone and I 5 skeletontelegraph-pole which shall be strong, held by nuts. The intermediatebrackets durable, and ornamental, and which shall be will be slipped onthe standards from the top light, portable, impervious to moisture, andbefore the top standard is secured thereto practically fire-proof; alsoto combine with and forced downward until they bind, where saidtelegraph-poles insulators of such conthey may be keyed, if desired. Itis prefer- 2o struction that they may be placed upon the able to usepiping for the standards, as rigidwires so as to incase them and besecured to ity is secured with lightness of construction. thecross-pieces of the pole without the use of It is obvious, however, thatangle bars or rods the usual dowel-pins, as hereinafter fully set mightbe used instead of the pipes without forth. departing from my invention.

25 \Vith these objects in view my invention The cross-pieces E, whichmay be conconsists in the special construction, combinastructed of woodor'metal in'the usual form, tion, and arrangement of the several partsof are secured to the upper ends of two of the the telegraph-pole,substantially as herein standards A B by eyebolts or staples c, whichafter described, and set forth in the claim. encircle the standards andextend through 30 Figure 1 represents in front elevation a me thecross-pieces, where they are secured by tallic telegraph-poleconstructed in accordnuts 0, the incline of the standards and posiancewith my invention; Fig. 2, a sectional detion of the eyebolts preventingthe crosstail of the post on dotted line .9300, Fig. 1, showpieces fromslipping down.

If desired, the lower bracket may be firmly secured to the lower ends ofthe standards by nuts or otherwise, with the ends of the bolts extendinga considerable distance below, so as to be buried in the ground, inwhich case the foundation-stone will. be dispensed with, or thestandards may have a pointed base, each to be driven into the ground,said base having longitudinal tapering radial ribs, as shown in Fig. i.
